Open-File Report 2011–1096
Scientists with the U. S. Geological Survey and The Ohio State University evaluated the effectiveness of chlorine dioxide (ClO2) as a wastewater disinfectant for onsite household sewage treatment systems. Effectiveness of ClO2 was measured by evaluating the removal of six test microorganisms: Escherichia coli, enterococci, Clostridium perfringens, Bacillus anthracis Sterne strain spores, somatic coliphage, and F-specific coliphage. These evaluations were done in bench-scale experiments and in a field-scale experiment where ClO2 was delivered to the sewage by use of a novel dry packet system. Results presented herein demonstrate effective inactivation of each test microorganism except for B. anthracis spores.
